Answer:
$1,950.00
Step-by-step explanation:
Total cost of shirts = $25 x 15 = $375
Total cost of shorts = $30 x 15 = $450
Total cost of shoes = $75 x 15 = $1,125
Total cost = $375 + $450 + $1,125
= $1,950.00

write a linear function to model the following situation:
An airplane is 30,000 ft. in the air and descending 1,000 ft. for each mile it travels.
descending means its going ____.
write the equation.
Y= _____________
or as a function
f(x) = 30,000 - 1,000x
the question is: How far away from the airport does the airplane have to start to descend to land safely? To answer that, we need to find the x- intercept
Answer:
x = 30
Step-by-step explanation:
To find the x intercept, you need to substitute [tex]y = 0[/tex], as all points on the x axis's y-coordinate is 0.
[tex]0 = 30000 - 1000x\\ \\ \to 0 + 1000x = 30000 \cancel{- 1000x + 1000x} \\\\ \to 1000x = 30000 \\ \\\to \frac{1000x}{1000} = \frac{30000}{1000} \\ \\\to x = 30[/tex]
Answer: Its x= 30

translation: 7 units right and 1 unit down/ J(-3, 1), F(-2, 3), N(-2, 0)
Answer: 7 units right and 1 unit down/ J(-3, 1), F(-2, 3), N(-2, 0)
J(-3, 1) = J'(4, 0)
F(-2, 3) = F'(5, 2)
N(-2, 0) = N'(5, -1)
Step-by-step explanation:
If you want to translate a point 7 units right, you'll need to add 7 to its x-coordinate. If you want to translate a point 1 unit down, you'll need to subtract 1 from its y-coordinate. Do both of these things to perform a translation 7 units right and 1 unit down.
So, we can write,
7 units right means add the +7
1 unit down means subtract the -1
Then,
J(-3, 1) = J'(-3 + 7, 1 - 1)
J(-3, 1) = J'(4, 0)
F(-2, 3) = F'(-2 + 7, 3 - 1)
F(-2, 3) = F'(5, 2)
N(-2, 0) = N'(-2 + 7, 0 - 1)
N(-2, 0) = N'(5, -1)
Therefore,
These points to make sure they have shifted 7 units right and 1 unit down.
7 units right and 1 unit down/ J(-3, 1), F(-2, 3), N(-2, 0)
J(-3, 1) = J'(4, 0)
F(-2, 3) = F'(5, 2)
N(-2, 0) = N'(5, -1)

Which of the binomials below is a factor of this expression?
100A²-498²
OA. A+ 7B
OB. 10A+7B
OC. A + B
OD. 10A+B
Answer: B. 10A + 7B
Step-by-step explanation:
To find the correct binomial, we will factor the given expression. I assume that by "-498²" you mean "-49B²".
This is a difference of squares:
(10A + 7B)(10A - 7B)
The binomial 10A + 7B is an answer option, so our answer is:
B. 10A + 7B

The grid above shows the graph of the parent function f(x)= |x| and a translated functions graph.
Use f(x)=|x| f(x) is shifted left 5 and shifted up 2 to create g (x). write the equation g(x).
The equation of the translated graph from the parent function is g(x) = |x + 2| + 1
How to write the equation of the translated graph?The parent function is given as
f(x)= |x|
From the graph, we can see that the parent function f(x) is translated as follows:
2 units left translation1 unit up translationThe above sequence of translation is represented as
(x, y) = (x + 2, y + 1)
So, we have
g(x) = |x + 2| + 1
Hence, the equation of the translated graph is g(x) = |x + 2| + 1

Find the y-intercept
Answer both.
The intercepts and the standard form of each polynomial are listed below:

The x-intercept correspond with each of the roots of the polynomial and the y-intercept is found by evaluating the expression at x = 0.
Now we proceed to find each element:
Case 1
x-Intercept
x = - 4 or x = 6
Standard form
f(x) = (x + 4) · (x - 6)
f(x) = x² - 2 · x - 24
y-Intercept
f(0) = - 24
Case 2
x-Intercept
x = 1 / 4 or x = 3
Standard form
f(x) = (2 · x - 4) · (x - 3)
f(x) = 2 · (x - 2) · (x - 3)
f(x) = 2 · (x² - 5 · x + 6)
f(x) = 2 · x² - 10 · x + 12
y-Intercept
f(0) = 12

How do the domains and ranges of the functions f(x)=√x-1 and g(x)=√x-1 compare?
The domain and range of the function f(x) is [1, ∞) and (0, ∞) and g(x) is (0,∞) and [-1, ∞).
Domain of function f(x) :
√ (x - 1) ≥ 0
So, we get that:
x ≥ 1
= [1, ∞)
Range = (0, ∞) as square of a number is always positive.
Domain of function g(x):
√ x ≥ 0
on adding 1 both sides we get
x ≥ 0
= (0,∞)
Range = [-1, ∞).
Therefore, the domain and range of the function f(x) is [1, ∞) and (0, ∞) and g(x) is (0,∞) and [-1, ∞).

What is Logarithm?The opposite of exponentiation is the logarithm.This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.Now,
log (x) - log (3) = 8
=> log (x) = 8 + log (3) = 8 + 0.477
=> log (x) = 8.477
Since, generally the base of log is 10, raising them to 10.
=> [tex]10^{log_{10}x} = 10^{8.477}[/tex]
=> x = 299916251.899 (as [tex]a^{log_a(x)} = x[/tex])

The perimeter of a rectangular pool is 160 meters. The length of the pool is 20 meters more than its width. What is the length?
Answer:
50 meters
Step-by-step explanation:
Width is x
So length will be x + 20
Perimeter = 2 (W + L) = 2 (x + x + 20) = 2 (2x + 20) = 4x + 40
so 4x + 40 = 160
4x = 120
x = 30
so length = x + 20 = 30 + 20 = 50
Which function is a phase shift of y=sin \theta by 5 units to the left?
(A) y=5 sinθ (C) y=sin (θ+5)
(B) y=sinθ+5 (D) y=sin 5 θ
Answer:
C.
Step-by-step explanation:
C describes theta moving +5 units. In math, negative goes left, negative goes left. However, since there are no negative values involved, we can assume that theta will move 5 units to the left in terms of absolute value, which excludes the need for the negative to be moved left. Therefore, the answer is C due to this change.

Check whether Samantha's equivalent expression is correct using x = 2.
A.)Samantha S incorrect because when
using x = 2, the resulting values in
both expressions are different
B.)Samantha is

C.)Samantha is correct
because when using x 2, the resulting values in
both expressions are equal.
Option C: Samantha is correct because when using x=2, the resulting values in both expressions are equal.
Consider, 4x + 2
When x = 2,
=> 4x + 2 = 4*2 + 2
=> 10
Now consider, x + 17 + 3x - 15
When x = 2,
=> 2 + 17 + 3*2 - 15
=> 10
Therefore, Samantha is correct as both expressions equal 10 when x=2.
In other words, if we consider, x + 17 + 3x - 15
=> x + 17 + 3x - 15
=> x(1+3) + 17 - 15
=> 4x + 2
This shows that for any value of x, the expression x + 17 + 3x - 15, simplifies to 4x + 2.
Therefore, both the expressions, 4x + 2 and x + 17 + 3x - 15, are equal.
